Why would I add an angle to the laser? You a bubble level. Use a strong laser.
Shine across a lake because you know it has to be unsubstructed by plants and stuff, and you make sure that you are pointing strait.
Do it 12 inches above the surface or 6 feet above. It's the same. Laser goes straight, that's how they work.
So, if the earth curves, then the target that is 12 inches exactly, above the water, or 6 feet, whatever, gets a laser pointer right on target. Ok if it's off by an inches., but it's not. Its maybe a cm or 2. Doesn't matter. The laser pointer should be off by more than 16 inches over just 2 miles.
It's just math and observations. You can do it yourself. Then go bitch at someone else about your crazy mental gymnastics you tried instead of just thinking logically for 2 minutes. You spastic fuck.
